A large meta-analysis found sperm concentration and total sperm count declined substantially over four decades. Male fertility is not something to take for granted.

Half of fertility cases involve male factors, but men are rarely the first to test. Get a six-marker hormone panel run in an ISO-certified German lab, with results read by a physician in 3–5 days.
“I'd never actually checked. Thirty minutes at the kitchen table and I finally knew where I stood.”
“We'd been trying for a year. Turns out it was me all along, and it was fixable. Wish I'd tested sooner.”
“Low testosterone, nothing dramatic. Caught it early, addressed it. The follow-up call was the best part.”
“I didn't know male fertility declined at all. This kit quietly changed how I think about the next five years.”
In roughly 50% of infertility cases, male factors contribute. Yet most evaluations start (and end) with the partner.
Sperm DNA integrity, motility, and concentration shift after 35, and those changes accelerate after 40.
Spermatogenesis takes roughly three months. Lifestyle and hormone changes become measurable the next quarter.
Lifestyle interventions, supplementation, or sperm cryopreservation. All more effective when started early.

Sperm carries more new DNA mutations as men age. One landmark Icelandic study estimated roughly two additional de novo mutations for every year of paternal age.

A large clinical cohort showed semen volume, sperm motility, and normal morphology all decline with age. Fertility shifts even when men feel perfectly healthy.

13 questions across age, lifestyle, medical history and symptoms — scored against ESHRE and AUA guidance. You get a personalised risk band and a clear yes/no on whether testing makes sense for you now.
Total + free Testosterone, FSH, LH, Prolactin, Estradiol and SHBG. Finger-prick sample, pre-paid return to an ISO 15189 lab, physician-reviewed report in 3–5 working days.
A short intake based on ESHRE guidance. Takes ~2 minutes.
Finger-prick sample in the morning. Pre-paid return label included.
Digital dashboard with physician notes and next steps in 3–5 days.
Sperm counts in the West have fallen by more than 50% since the 1970s, and male factors drive roughly half of all fertility cases. We're a Berlin team working with German andrology clinics, ISO-certified labs and university hospitals to give men the same diagnostic standard their partners already have. Hormones now. Sperm analysis next. Cryopreservation after that.
Six-marker at-home blood panel with physician review.
At-home donation kit with overnight-shipped analysis. Motility, count, morphology, DNA fragmentation.
Partner-lab freezing and long-term storage, managed through the FutureKit dashboard.
Expanding beyond male fertility: AMH-based ovarian age assessment and clinic-partnered egg freezing.
